ORIGIMAGIC C4 Plus
Published on
The ORIGIMAGIC C4 Plus is a 5-inch-square mini PC built around the AMD Ryzen 5 3501U, a 15W quad-core chip with Radeon Vega 8 graphics. Two Gigabit Ethernet jacks sit on the back panel next to HDMI and DisplayPort, and the carton includes a VESA bracket for hanging the box behind a monitor. It ships with 8GB of DDR4 and a 256GB M.2 drive, both upgradable, and Windows 11 Pro is pre-installed.
Pros and Cons

The chip is a 2026 reissue of a 2019 design
AMD lists the Ryzen 5 3501U with a Q2 2026 launch date, four cores, eight threads, a 2.1 GHz base clock, a 3.7 GHz boost, 4MB of L3 cache, and a 15W default TDP configurable between 12W and 35W (AMD product page). The same page puts the CPU cores on a 12nm process, which is the Zen+ generation AMD shipped in 2019, and pairs them with Radeon Vega 8 graphics running at 1200 MHz. Some retail spec tables call the chip a Ryzen 5 3500U; the product titles and AMD’s own page say 3501U.
PassMark’s database gives the 3501U a CPU Mark of 6578 and a single-thread rating of 2016 from six submitted samples (cpubenchmark.net). The Ryzen 5 3550H in the ORIGIMAGIC COMET C4 sits at 7610 in the same database, and that box lists between the two C4 Plus configurations while carrying 16GB of memory and a 512GB drive. Against the $299.99 NVMe configuration, the C4 Plus asks more for less CPU and half the memory, so the second Ethernet port has to be the reason you are buying. The cheaper SATA configuration undercuts the COMET C4, and there the extra NIC costs you CPU rather than money.
Ports, memory, and what upgrades are possible
The rear panel carries the DC barrel jack, both RJ45 jacks on Realtek RTL8111H controllers, HDMI 2.0, DisplayPort, one USB 3.2 Gen 2 Type-A port, and one USB 2.0 port. The front face holds two more USB 3.2 Gen 2 ports, a USB-C port, a 3.5mm combo audio jack, and the power button. HDMI and DisplayPort each drive 4K at 60Hz; the USB-C port is limited to 5Gbps of data and 1080p of video, so a third screen runs at the lower resolution.
One 8GB DDR4 SO-DIMM ships installed with the second slot free, and the pair tops out at 32GB. There are two M.2 2280 slots: the 256GB boot drive fills one (SATA on the cheaper configuration, NVMe on the other) and the free slot takes an NVMe PCIe 3.0 x4 drive of up to 4TB. There is no 2.5-inch bay. Wireless is WiFi 5 and Bluetooth 5.0.
Who this box suits
Two Gigabit ports on a machine this small and this cheap is the argument for the C4 Plus. A small OPNsense or pfSense router, a firewall in front of a home network, or a lightweight file server all want a second NIC, and buying one on a card costs money and space that a 5-inch box does not have. The 15W chip and the 32GB memory ceiling are adequate for that kind of always-on, low-load duty.
As a general desktop it is harder to justify. The COMET C4 gives more CPU and ships with 16GB and a 512GB drive while listing under the $299.99 NVMe configuration, and anyone who needs WiFi 6E or a faster chip should look at a newer model such as the ORIGIMAGIC A1. No independent testing of this model has been published; the numbers above are AMD’s specifications, PassMark’s database, and the retailer’s own figures. Starry Hope’s Mini PC Comparison Chart lines these specs up against the rest of the catalog.
Frequently Asked Questions
What processor is in the ORIGIMAGIC C4 Plus?
An AMD Ryzen 5 3501U with 4 cores, 8 threads, a 2.1 GHz base clock, and a 3.7 GHz boost. AMD lists it with a 15W default TDP, a 12nm process, and Radeon Vega 8 graphics at 1200 MHz.
Why does the C4 Plus have two Ethernet ports?
Two Gigabit jacks on Realtek RTL8111H controllers let the box bridge two networks, aggregate bandwidth, or act as a router or firewall between a modem and a switch. For a plain desktop with one wired connection, the second port goes unused.
How much RAM and storage can the C4 Plus take?
Two DDR4 SO-DIMM slots hold up to 32GB between them. There are two M.2 2280 slots: the 256GB boot drive fills one, and the free slot takes an NVMe PCIe 3.0 x4 drive of up to 4TB. There is no 2.5-inch SATA bay.
Can the C4 Plus drive three monitors?
Yes. HDMI 2.0 and DisplayPort each output 4K at 60Hz, and the USB-C port adds a third display capped at 1080p.
How does the C4 Plus compare to the ORIGIMAGIC COMET C4?
Both carry dual Gigabit Ethernet and the same port layout. The COMET C4 uses the H-series Ryzen 5 3550H, which PassMark rates at 7610 against the 3501U’s 6578, and it lists between the two C4 Plus configurations with 16GB of RAM and a 512GB drive. The C4 Plus is the lower-power part at a 15W default TDP.
What operating system ships on the C4 Plus?
Windows 11 Pro is pre-installed. ORIGIMAGIC states the machine also runs Linux, and the BIOS exposes wake-on-LAN and auto power-on settings.
